Baku in winter, the wind is cold. The rich Transcaucasian style, mixed with Muslim charm, can be found in every corner of the city.

If you stand in the center of Baku, this city modified by the Soviets and surrounded by mountains and seas can still be called stylish. However, the farther away from the city of Baku, the less "wind" there is, and the heavier the steel and black oil becomes, until the place where the thick blows cannot be dispersed, which is the core of the Baku oil field.

In the former Baku oil field, the workers enjoyed the wind of the sea, the sunshine of the sea, the respect of the sea and the income of the sea.

Today's Baku oil fields, like all those old industrial bases that have lost their power, are left with heavy steel, rusty steel, depressed steel and disillusioned steel.

It's like a jungle of lost hope.

The only dozens of Azerbaijani oil workers stopped what they were doing and watched with disdain and curiosity as a dozen Chinese workers re-examined the scene. They don't really have much work to do, and they have time to squander.

Although there is oil extraction equipment everywhere, it is easy to distinguish between equipment from China and equipment from the former Soviet Union. Most of Dahua's equipment is painted dark blue, and the equipment without painting is also treated with a metal finish, which is quite eye-catching.

Lin Yonggui looked at the group of equipment that he couldn't see the edge, and said in surprise: "Need so many things?"

"Tertiary oil recovery is also a new technology for us, and it is not yet time to control the volume. Su Cheng smiled slightly and exclaimed, "Dean Qin, you can explain it to us." ”

"Oh, let's stand tall. Qin Shiwei was like a giant bear, quickly climbing a large cement pier more than one meter high, which instantly made the group of guys in suits and leather shoes below look dumbfounded.

When Qin Shiwei arrived in Dahua, he still insisted on "physical exercise" in the metal laboratory. His left arm is getting thicker and thicker, he is taller, and now he is looking at people from a bird's-eye angle, which suddenly makes others have a kind of "Am I a big horse monkey?"

Su Cheng looked down at the new trousers, coughed, and said, "Dean Qin, just talk about it, don't stand so high." ”

"If you don't stand up, how far can you see? "Dean Qin has never considered the feelings of others. This is also used to being used by state-owned enterprises, and for a role like him, the directors of various oil production plants have to hold him in a kneeling and begging way all year round. Correspondingly, in addition to studying majors, Qin Shiwei does not need to consider the feelings of others.

Of course. Sioux City is also a fuel for the trouble. For a researcher like Qin Shiwei, Su Cheng has always had reasonable requests to be satisfied, and unreasonable requests have been carefully considered.

So, after fifteen seconds of careful consideration, Sioux City decided to climb up.

Gu Hongjun helped him to help, and Azerbaijan No. 1 and Azerbaijan No. 2 were stuck on both sides of Sioux City simultaneously, as if he was afraid that he would be assassinated.

Lin Yonggui also knew Qin Shiwei. However, it is only limited to the perception of a "good senior engineer". He spent more time lamenting his old arms and legs, and finally stepped on a staircase made of several wooden boxes and stood on top of the concrete pier.

The cement pier is quite large, and there are more than 20 people standing in it. The horizon has also broadened a lot.

Qin Shiwei remembered Su Cheng's advice, and when Lin Yonggui came up, he opened his mouth and said: "What you see now is the ground process equipment for three oil extractions. It's complicated. Broadly classified, on the left is the polymer dispersion and dissolving device. Then there are the irrigation systems, feeding systems, injection systems, and process control systems. A single maturation irrigation system takes up all the space over there. ”

Lin Yonggui followed Qin Shiwei's finger and looked, it was really a big place.

At least the size of a department store, it was divided into three areas, built with board houses, and placed equipment.

Qin Shiwei didn't care whether they could understand it or not, and continued: "Just here for the maturation irrigation group, there are low-pressure water supply rooms, surfactant seepage rooms, polymer feeding rooms, valve group rooms, power distribution rooms, spare parts and maintenance rooms...... In addition, there are sterilization rooms, laboratories, unloading workshops, duty rooms, restaurants, and shower rooms under the warehouse......"

As soon as he explained this, the board house below, which looked like a container placed indiscriminately, came alive in the eyes of everyone.

"I see that a lot of equipment is still exposed, is this in a hurry or?" Lin Yonggui wanted to help so much that he immediately asked again.

Qin Shiwei said a little proudly: "Our injection station is a combination of skid-mounted and fixed-type equipment, and most of the exposed ones are skids. ”

The oilfield skid is the modular production component of the oilfield, and a skid is equivalent to an integrated circuit version of electronic products. They are often composed of a unified base, which can fit many pipes, valves, equipment and even instruments into it, and complete a certain function at the same time, such as heat exchange, air exchange, pressure regulation and so on.

When you arrive at the site, as long as you assemble the required skids, you can quickly get a gas station, like building blocks.

The skid-mounted dispensing station is the fastest dispensing station, and the skid-mounted dispensing station of later generations often only needs six or seven skids to achieve all functions.

Dahua Industry has carried out this work for four years, and has not yet been able to achieve 100% skid-type production, despite this, the skid-mounted and fixed combined dispensing station is also the only leading technology in China, and has dozens of international patents.

A few foreigners didn't even need to translate, but they saw this, and kept spitting out syllables such as "skid" and "package".

Lin Yonggui didn't take it seriously, nodded and passed.

Qin Shiwei threw his eyes at the man, and he was not angry, he turned his head and asked Su Cheng, "Then shall we start?"

"Let's get started. ”

"Start filling the water. Qin Shiwei shouted, and the control room below was busy.

At the same time, Yang Ming handed over the prepared information to everyone present and said: "At present, the test production well number 011 adopts fracturing operations, and the current average daily production of liquid is 94 tons, oil production is 32 tons, and the water cut is 65%. Our goal is to have a single well injection pressure of 11MPa, a daily injection volume of 170 cubic meters, and a dependent suction coefficient of 155 cubic meters per megapascal ......"

"Fracking?" said Gilles, a representative from the French company Fina, who repeated the word in French and then asked in English, "Why fracking?"

"Get more oil. Qin Shiwei looked at him with the same eyes as he looked at Lin Yonggui.

"You've done the fracking, and how did you do it?" Finer is the second largest oil company after Total and the candidate partner Sioux City has chosen. This time, they didn't send out the beautiful girls from before, but chose the guys who know technology. The person also swept away the lazy look in front of him and became a little focused.

Qin Shiwei didn't care about the other party's technical passion, and deliberately said: "The fracturing operation has been patented, and communication is not allowed." ”

Patented technology can only form barriers, and it is better to hide the technology itself. After so many years of expansion, the Information Bureau has also tightened its control in this regard.

A representative of Fina pressed up: "You expect that after fracturing operations, than non-fracking wells. How much more can I increase my output?"

"About 20%, this is mainly to improve the conductivity of the low permeability layer of the injection well and improve the oil displacement effect of polymer flooding. ”

"What about fracking?"

"Not much. ”

"Can you go down and take a look? I mean look at the control room. ”

"Yes. "Sioux City is here to show off, where will it refuse to be seen.

Gilles' positive attitude influenced the others, and a group of people crowded around and headed to the control room.

Lin Yonggui is not at ease when he is left behind. He's seen too many stories of misrepresentation of production. But this is Azerbaijan, and he fears that Sioux City is ill-prepared.

After thinking about it, Lin Yonggui still found his secretary and ordered in a low voice: "Find someone over, find one more person who understands the equipment, I think this tertiary oil recovery equipment is very complicated." ”

Lin Yonggui had already decided to help Su Cheng cheat, more precisely. It is to prevent Sioux City from cheating, and add a double insurance. If it was on his own turf, he was sure that he could increase his output as much as he wanted, but here. He can't guarantee it.

There was a loud rumbling sound of the equipment below, but it was the pouring of water below that began.

Lin Yonggui paced slowly, and listened to a group of people discussing in various languages, and it was a mess. Qin Shiwei looked bad, his face was red.

Lin Yonggui asked Xiaopang in a mocking tone: "Are you messing with your father-in-law again?"

"How dare I. Xiaopang looked at Qin Shiwei's left hand. With a frightened face, he said in a low voice: "They asked Dean Qin about the details of the polymer, but Dean Qin didn't say it, so they said that Dean Qin didn't understand, and then discussed it themselves." ”

"Such a simple method of agitation ......"

"It's really annoying, as soon as Dean Qin retorted, they asked for details, and Dean Qin couldn't say it, so they said that Dean Qin didn't understand. ”

"That's him. Lin Yonggui shook his head, didn't care on the surface, and asked again after a while: "Then you say, does Lao Qin really understand or fake it?"

Qin Shiwei's sharp eyes passed through several people and stared at them.

Xiao Fat shrank his neck and said solemnly: "Of course Dean Qin really understands, he knows everything and is omnipotent. ”

Qin Shiwei turned his head without any expression, and continued to argue in English: "After our systematic analysis, the medium molecule polyacryloyl is the most economical polymer at present, as long as we wait until tomorrow, we can verify this." ”

"The effect of low molecular weight polyacrylamyl will be significantly better, although the yield will be higher, but the increment should be significantly improved. ”

"What about binary drives? With binary drives, it is not a problem to increase oil to 20 tons per ton, I heard that Shell's laboratory research has been completed. ”

"The way forward in the future is carbon dioxide flooding. The steam drive is also very vigorous. ”

The number of people who speak does not decrease, on the one hand, they are in a hurry to wait, and on the other hand, they are also confused and deliberately belittled.

The suspect is the buyer, Su Cheng listened with a smile, unmoved.

Theoretical things can't be discussed in a day, and he doesn't bother to participate.

In the tertiary oil recovery technology, there are polymer flooding, steam flooding, carbon dioxide flooding, microbial flooding, only polymer flooding, as well as the advancement of one-element flooding, two-way flooding, and three-way flooding. In terms of the size of polymers, there are medium molecular weight, low molecular weight, high molecular weight, ultra-high molecular weight, cationic and so on......

Dahua Industrial has studied which method to do tertiary oil recovery for more than four years, and the current plan selected is the most mature and economical plan.

The low molecular weight, or binary driving of clouds, as others say, is indeed good, but the success is also high. Perhaps, large foreign companies can reduce their growth even lower, but from the perspective of Dahua Industry, medium molecular polyacryloyl is the best choice.

However, this kind of conclusion made with money cannot be said casually. Qin Shiwei also knew this, and there was no way to be squeezed, so he had to emphasize repeatedly: "Wait until tomorrow, you can verify it." ”

Naturally, representatives of the major oil companies did not buy it and simply discussed it with each other.

Lin Yonggui became more and more worried, this is not only a question of how much oil is produced from the oil well, but also a problem with polymers, and there are too many places that are easy to expose.

He was there worried about Sioux City, but he didn't notice that there were always several representatives or attachés of foreign companies, staring at the instruments in the control room.

The amount of injection, the concentration of the polymer solution, the injection pressure, the concentration of the surfactant, etc., are the focus of their attention.

Tertiary oil recovery technology with practical value is attractive to any company that controls the oil field.
